Definitions

  • This invention is related to backlighting a liquid crystal display (LCD) panel and, in particular, to backlighting an LCD panel with light emitting diodes (LEDs).
  • LCD liquid crystal display
  • LEDs light emitting diodes
  • CCFLs cold cathode fluorescent lamps
  • a direct backlight type is used, where the lamps are directly placed behind the LCD, as shown in Fig. 1A.
  • Fig. 1A shows the CCFLs 10, a diffuser plate 12, and an LCD panel 14. Disadvantages of using CCFLs are that they require mercury, have a low color gamut, and have a limited brightness.
  • a collimating means is used to limit the crosstalk between the LCD pixels and the phosphor dots. Both applications have the advantage that the color uniformity is determined by the phosphor and the phosphor printing process, and that the system efficiency can be very high, as the absorbing color filters are no longer needed. However, efforts in this area have not yet resulted in introduction of this technology to the market.
  • One embodiment of the invention provides a backlight for an LCD display, having a high efficiency, good color uniformity, and spatially and temporal adjustable luminance profile, for obtaining better contrast and lower power consumption at a low cost.
  • the backlight uses an array of single color or white LEDs and a diffusing or phosphor coated cover plate. To obtain a high efficiency, no additional optics is used in between the LEDs and the cover plate. In this invention, a good compromise has been found between color and flux mixing properties of the LEDs and control over the luminance profile.
  • Fig. 2A is a side view of an LCD display 22.
  • An array of LEDs 24 is placed on the rear panel of the backlight 26.
  • the backlight 26 is covered with a diffusing cover plate (diffuser 28).
  • the diffuser 28 is for example made of acrylic or glass, with a roughened surface for diffusing light. Alternatively, the diffuser 28 may have light scattering particles with the acrylic or glass sheet.
  • Many types of diffusers are known and may be used with the backlight 26.
  • a transparent plate may be used instead of the diffuser 28 if the light output of the backlight 26 is sufficiently diffused without a diffuser.
  • Additional films (not shown) for increasing the brightness or efficiency might be used on top of the diffuser, just before the LCD, as for example Brightness Enhancement Film and Dual Brightness Enhancement Film, as for example produced by 3M.
  • the back plane 30 and the sidewalls 32 of the backlight 26 are covered with high reflective materials.
  • Good results have been obtained with a white diffuse reflective film on the back (e.g., E60L, produced by Toray, Japan), and a specular reflecting material on the sidewalls (e.g., Miro material, as produced by Alanod, Germany), but other configurations work as well.
  • the materials used should have a high coefficient of reflection, preferably >90%. By using these high reflective materials, a high recycling efficiency is achieved. This is in particular important when Brightness Enhancement Films are used, as mentioned above, as these films reflect the light which can not be used in the first pass, and which needs to be recycled in order to contribute to the output of the LCD during a second or third pass.
  • the LCD panel 14 is placed in front of the backlight 26.
  • the LCD panel 14 may be a conventional LCD, having a first polarizing filter, a thin film transistor array for developing an electric field across selected areas of the liquid crystal layer, a liquid crystal layer, an RGB color filter array, and a second polarizing filter.
  • the color filter array has red, green and blue subpixels.
  • additional films can be used, such as a brightness enhancement film (BEF) or polarization recovery film (DBEF).
  • Figs. 3A and 3B show The preferred intensity profiles of each LED 24 for obtaining a good balance between light mixing and luminance control.
  • Fig. 3A shows an example of a Batwing type intensity pattern
  • Fig. 3B shows a so-called Lambertian radiation profile.
  • Lumileds LXHL-BW01 & LXHL-BR02 for the batwing white and blue
  • LXHL-PW01 & LXHL-PR03 for the Lambertian type white and blue.
  • Fig. 4 shows the preferred relationship between the total thickness (H) of the backlight 26 and diffuser 28 and the pitch (P) of the LEDs 24.
  • H total thickness
  • P the pitch
  • the pitch of the LEDs used in the present backlight is 20mm or greater.
  • Fig. 5 shows one example of the layout of the LEDs 24 in the backlight 26.
  • the LEDs 24 are placed in a square pattern using 36 LEDs.
  • the actual number of LEDs needed depends on the size of the display, the luminous flux of each LED, and the required brightness. As LEDs do vary in light output and efficiency with production tolerances, and for a cost effective solution all LEDs have to be used (high yield), and in general the center of the display will have a higher brightness (luminance) than the edge of the display, it is preferred to put the most efficient, highest output LEDs in the center of the backlight and the less efficient dimmer parts near the edge of the backlight.
  • FIG. 6 An alternative configuration of an LED layout is shown in Fig. 6, where a layout using 31 LEDs is shown, and where the LEDs are places in a hexagonal structure.
  • This layout has the advantage that each LED has six equidistant neighbors, and that the brightness of individual LEDs are averaged over its neighbors.
  • Fig. 7A illustrates an arrangement where in between the LEDs 24 a light sensor 34 is placed to measure the luminance (brightness) uniformity over the backlight 26. Of course, placing the sensors 34 at larger spacing than the LEDs can lower the number of sensors. A preferred configuration is where the spacing of the sensors is between 1x and 3x the spacing of the LEDs.
  • Fig. 7B illustrates one type of circuit that detects the sensor 34 signals and controls the LEDs or LCD panel to compensate for degradation of the LED brightness.
  • the detector 36 samples each sensor 34 output using any suitable technique, such as by multiplexing.
  • a sensor 34 that measures a reduced light output is associated with one or more specific LEDs 24 in the array or a group of pixels in the LCD panel 14.
  • a control unit 38 such as a current supply for the LEDs or an LCD controller, then adjusts the current to the affected LEDs or controls the gray scale level of the affected LCD pixels to compensate for the brightness degradation. Other suitable techniques may be used.
  • Fig. 8A shows an electronic driving scheme for the backlight 26.
  • 31 LEDs 24 are connected in series.
  • Such a configuration is especially suited to reduce the costs of an electronic driver or inverter, as the forward voltage per LED is approximately 3.5V, and the total voltage of 31 LEDs in series approximates 110V, which is the standard supply voltage in the U.S. and Japan.
  • the driver can consist of a simple rectifier and smoothing capacitor to drive this string of LEDs. More or less LEDs would be connected in series depending on the voltage drop across each LED or the power supply voltage.
  • Fig. 8B shows a similar configuration, but for a bigger backlight and using four strings of approximately 31 LEDs.
  • the four strings of LEDs could even be used as diodes in the power supply full-wave rectifier, reducing the costs of the driver even further.
  • a preferred embodiment of the invention is where the LEDs are driven in groups, where the LEDs are connected in series, and where the forward voltage of each group matches the supply voltage of the power grid. For the U.S. and Japan, where this voltage is about 110V, every group would contain between 28 and 37 LEDs in series. For Europe and other countries, this supply voltage is between 220 and 240V, resulting in about 60 to 80 LEDs per group.
  • Fig. 9 An extreme example for this category is shown in Fig. 9, where every LED can be driven independently.
  • the LEDs are connected in a matrix, and the LEDs can be driven row at a time, or column at a time, where every LED in a row or column can be driven at a different power.
  • the row-at-a-time option is attractive, since it resembles the way images are produced on a cathode ray tube (CRT), and the motion artifacts are greatly reduced.
  • FIG. 10 A different driving scheme, where the LEDs 24 are driven in groups between three and seven LEDs, is shown in Fig. 10.
  • the hexagonal structure is used for 14 groups, where each group can be driven independently.
  • Fig. 11A shows a simple geometry where the LEDs 24 are connected in series per row, and each row can be operated independently.
  • This example shows six LEDs per row, but of course the actual number of LEDs depends on the size, thickness and brightness of the display. In this configuration, the brighter LEDs would be placed in the center of the display, while the dimmer parts would be placed towards the side of the backlight.
  • FIG. 11B An example of such geometry for a bigger display, where the left half of the display can be driven independently of the right half of the display, is shown in Fig. 11B.
  • this configuration can be extended to operate the backlight in three segments as well, which is preferable for the large wide format screens.
  • Fig. 12A shows a backlight configuration when only blue, UV, or near-UV LEDs are used, and where the color-converting phosphor layer 39 is on the cover plate 40.
  • the cover plate 40 may or may not be a diffuser, depending on the amount of diffusing performed by the phosphor.
  • the phosphor layer 39 is a uniform layer, consisting of one or more different type of phosphors. Preferably, a green and a red phosphor are used, but a yellow (YAG) phosphor could be used as well.
  • This layer 39 can, for example, be applied by spray painting, screen-printing, or electrophoretic deposition, or might be a film with uniform density of particles or a luminescent dye distributed throughout the film.
  • This configuration is attractive because the phosphor is not on top of the LED die, and light emitted from the phosphor to the rear of the backlight 26 has a larger recycling efficiency than into the LED chips, due to the high reflectivity of the films used in the backlight 26. And in addition to the recycling efficiency, the phosphor can be operated at a lower temperature and does not have chemical compatibility issues with the LED die, improving the efficiency and lifetime considerably. From a logistics point of view, this solution is attractive as well, as the blue backlight can be used for a large range of different displays, with different types of color filters, and only the phosphor layer thickness and phosphor concentration has to be optimized to fit a particular LCD.
  • blue LEDs 24 are used that match the desired blue pixel color of the LCD, then some blue-light transmissivity of the green-red phosphor layer is desirable so that red, green, and blue light components are transmitted to the LCD.
  • one type of phosphor is applied to the cover plate 40, preferably the green or amber phosphor, while another phosphor, preferably the red phosphor, is applied to the rear panel 48 of the backlight configuration.
  • the rear panel acts as a diffuser.
  • This phosphor is not applied as a uniform coating, but is applied as a dot pattern.
  • the combination of blue light from the LEDs and the red and green light from the phosphor layers produces a substantially white backlight for the LCD panel.
  • Fig. 12B shows an alternative configuration, where the phosphor is integrated into the cover plate 42.
  • Cover plate 42 may or may not provide additional diffusion, depending on the diffusion performed by the phosphor.
  • Fig. 12C shows another embodiment, in which a uniform phosphor coating 39 is applied directly onto the LCD 14, more specifically, on the TFT array glass. Applying phosphors to glass is a well-developed and inexpensive process. Furthermore, by integrating the phosphor onto the LCD, the number of parts is reduced.
  • Figs. 13A and 13B show a configuration where a phosphor bulb 44 or 46 is formed around the blue LED 24, effectively creating a white lamp.
  • the mixing is done in two stages, first in the bulb, and second, between the bulb and the diffuser 28.
  • this configuration has the benefit that the amount of phosphor used is smaller than it would be had the phosphor coated the cover plate.
  • phosphor is deposited directly on the LED chip.
  • red, green, and blue LEDs in the array may be used if the pitch is small enough, it is preferable to use either all LEDs of a single color or white light LEDs (e.g., using a phosphor bulb) to obtain better color uniformity at the output of the backlight.
